If you can find the clay based litter, it does work in a panty hose leg or any other cloth sack. You can dry it out by putting it in the oven on a low temp for a bit until dry if the weather does not allow for drying outside. I wouldn't try that with the other kinds of litter for fear of toxic fumes when heated.

I have the same problem (mostly in my craft room) & I've been wondering the same thing. I looked into buying a REAL dehumidifier machine, but they need a drainage line drilled for the water to escape from. Maybe you could empty them twice a day. They cause around $200, but I'm sure they are WELL worth the cost!

I've found that descant in bulk is MUCH cheaper than in individual packets & they have it a Lowell's & maybe also at Home Depot. Make sure you keep the bulk container sealed well or put the stuff into a large zip-lock bag or jar so it stays fresh! (maybe you could buy it bulk on line) I've also found the price varies greatly from store to store. So it pays to shop around!

* One tip I've read that can help suck moisture from the air is: You take a leg from a pair of old pantyhose & fill the leg up with cheapie clay-based cat littler then hang this in your closet. The littler will suck moisture from the air. After several days, you put the leg full of litter in the hot sun to dry then switch out with a new one while the old one dries out. This "recipe" was originally posted for moist or moldy car trunks, but I'm sure it would also work for a closet.

? I've often wondered if the newer cat litters that "clump" might work better because the litter is made to suck up quite a bit of moisture, but I have no idea if this would work. There's also the newer "crystal" based cat litter, it holds about 10 times it's weight in moisture. It's also worth a try (in the pantyhose leg). The trick is to be able to re-use the litter by drying it out in a hot place (maybe inside a hot car as it sits in the sunshine?).
